We answer your questions.
The most frequent questions from engineers and customers — with specific answers.
Will it fit my air ducts?
Standard flange dimensions per EN 1506 (TFC/TCD) and GOST 14911. Fits directly to your existing ductwork without adapters. If required, we can manufacture to your dimensions.
How airtight is it, really?
Tightness class 3 per EN 1751 — leakage less than 10 m³/(h·m²) at 500 Pa. Each batch is tested on a rig. We send the test report with the order.
Which actuator should I choose?
For standard systems — manual actuator (40% savings). For automated systems — electric actuator 230V (open/close 60 sec). For smoke extraction systems — spring return actuator 24V.
Can it be installed by oneself?
Yes. Weight 3-15 kg depending on size. Installation in 15 minutes: 4 flange connection bolts. We include instructions in Russian and installation video.
